WikiAsp: A Dataset for Multi-domain Aspect-based Summarization

This repository contains the dataset from the paper "WikiAsp: A Dataset for Multi-domain Aspect-based Summarization".

WikiAsp is a multi-domain, aspect-based summarization dataset in the encyclopedic domain. In this task, models are asked to summarize cited reference documents of a Wikipedia article into aspect-based summaries. Each of the 20 domains include 10 domain-specific pre-defined aspects.




WikiAsp is a available via 20 zipped archives, each of which corresponds to a domain. More than 28GB of storage space is necessary to download and store all the domains (unzipped). The following command will download all of them and extract archives:

./scripts/ /path/to/save_directory

Alternatively, one can individually download an archive for each domain from the table below. (Note: left-clicking will not prompt downloading dialogue. Open the link in a new tab, or save from the context menu on your OS, or use wget.)

Each domain includes three files {train,valid,test}.jsonl, and each line represents one instance in JSON format. Each instance forms the following structure:

    "exid": "train-1-1",
    "input": [  
        "tokenized and uncased sentence_1 from document_1",
        "tokenized and uncased sentence_2 from document_1",
        "tokenized and uncased sentence_i from document_j",
    "targets": [ 
        ["a_1", "tokenized and uncased aspect-based summary for a_1"],
        ["a_2", "tokenized and uncased aspect-based summary for a_2"],


  • exid: str
  • input: List[str]
  • targets: List[Tuple[str,str]]

Here, input is the cited references and consists of tokenized sentences (with NLTK). The targets key points to a list of aspect-based summaries, where each element is a pair of a) the target aspect and b) the aspect-based summary.

Inheriting from the base corpus, this dataset exhibits the following characteristics:

  • Cited references are composed of multiple documents, but the document boundaries are lost, thus expressed simply in terms of list of sentences.
  • Sentences in the cited references (input) are tokenized using NLTK.
  • The number of target summaries for each instance varies.
